a bonobo humanity?

Jacinta: So we heard recently, on an SGU podcast, that more CO2 was pumped into our atmosphere in 2022 than in any previous year, in spite of more people and governments being on board with combatting global warming than ever before.

Canto: Yes, depressing but unsurprising, with the population continually rising and, more importantly, more of the global population catching up with the WEIRD world. We can only hope that the increase in CO2, and greenhouse gases generally, will slow, and soon be reversed, as will the population. I mean, the population needs to stabilise, like ZPG, and the greenhouse effect needs to be reversed.

Jacinta: Well what the SGU has highlighted is that Germany, and not just Germany, is closing nuclear power plants much more readily than fossil fuel production, or fossil fuel imports, because… why?

Canto: Because of the overblown reaction to the Fukushima disaster, which, if cool heads prevailed, should not have affected a country that doesn’t tend to be hit by tidal waves, that doesn’t suffer from the ‘managerial capture’ and the problems in nuclear safety management that plagued the Japanese nuclear industry…

Jacinta: But there’s also the long lingering concerns about nuclear energy, in Germany and globally, as I recall from the days way back in the 1980s when there were big protests about our uranium exports here in Australia, which I must admit to being involved in. Fears about nuclear radiation were at quite a height then, what with the Maralinga tests in South Australia, our state, in the 1950s and 60s. The blast sites were still found to be highly contaminated in 1985.

Canto: So – Three Mile Island, Chernobyl and Fukushima – three nuclear incidents from which we’ve learned a heap. And from all the testing done in the Pacific, by the USA and France, and maybe others. The USA’s last test there was done in 1962. They continued doing stuff in Nevada till 1992. The French kept on testing at Mururoa until 1996, but as we know, the protests just kept growing and growing, and it all seems to have ground to a halt.

Jacinta: Never say never. So the Green Party in Germany were very anti-nuclear, and they forced an agreement with the government in 2000 to phase out nuclear energy by 2022. Later, Angela Merkel’s government managed to extend the phase-out date to 2034, but then Fukushima happened, and the date was put back again to 2022. They were on track to do that, but Putin’s invasion of Ukraine delayed it slightly. They’ve just closed the last nuclear power facility.

Canto: So, according to the SGU, Germany’s energy production spread in 2010 was 60% fossil fuels, 23% nuclear and 17% renewables. In 2022 it had changed to 51% fossil fuels, 6% nuclear and 43% renewables, which isn’t bad, but clearly if they hadn’t abandoned nuclear, that might’ve reduced the fossil fuel load by another 20% or so.

Jacinta: Lies lies and damn statistics. Shoulda-coulda-woulda. So, seriously, as Steve Novella points out in his SGU rant, we should be focussing on phasing out fossil fuels – coal first, as the dirtiest, then oil, then gas – and keeping nuclear going as a fairly long stop-gap in the medium term.

Canto: They’ve got a whole transcript of the podcast online, I’ve just discovered. And one of the points Novella makes is that you have to look at the path to achieving zero emissions. Germany already has the nuclear infrastructure, as do other European countries, such as Sweden (which almost went the way of Germany), so rebooting its nuclear facilities would be far less costly than starting from scratch as we’d be doing in Australia, where there’s absolutely no appetite for nuclear…

Jacinta: And we’re perfect for solar and storage, and offshore wind. Anyway, as a result of Germany’s decision it’s the third highest CO2 emitter in Europe, behind Poland and the Czech Republic, and the figures are extremement revealing. Germany releases 385 grammes of CO2 per kWh, compared to nuclear-powered France, at 85, and Sweden, which has a lot of hydro, at 45 – the lowest in Europe.

Canto: Tasmania, which is all hydro, boasts about its negative emissions, since it exports a proportion of its energy.

Jacinta: Italy is up at 372, having got rid of its nuclear generators.

Canto: Hell in a hand-basket.

Jacinta: So they describe nuclear as a bridging technology…

Canto: But what do they do with all the waste? Radioactivity and all?

Jacinta: Good question. A quick search turns up this:

Over 60,000 tons of spent nuclear fuel are stored across Europe (excluding Russia and Slovakia), most of which is in France. Within the EU, France accounts for 25 percent of the current spent nuclear fuel, followed by Germany (15 percent) and the United Kingdom (14 percent).

That’s from a ‘World Nuclear Waste Report’ in 2019, from an organisation called Focus Europe. They say that only Finland has ‘a permanent repository for the most dangerous type of waste’.

Canto: So, all the more reason to focus on renewables, but wth nuclear being a part of the mix for the foreseeable,  storage is a big issue, and then there’s the Ukraine situation. ..

Jacinta: And a controversial situation in the Balkans, on the Croatia-Bosnia border, but you go first.

Canto: Well, we’re talking about the Zaporizhzhia plant in south-eastern Ukraine. The World Nuclear Association  is presenting a timeline of all the distressing events from the start of the invasion to the present. Interestingly, Russia captured Chernobyl at the beginning of their invasion, but then thought better of it. Here’s how Wikipedia describes it:

During the 2022 Russian invasion of Ukraine, Chernobyl became the site of the Battle of Chernobyl and Russian forces captured the city on 24 February. After its capture, Ukrainian officials reported that the radiation levels started to rise due to recent military activity causing radioactive dust to ascend into the air. Hundreds of Russian soldiers were suffering from radiation poisoning after digging trenches in a contaminated area, and one died. On 31 March it was reported that Russian forces had left the exclusion zone. Ukrainian authorities reasserted control over the area on 2 April.

The whole Chernobyl debacle – it’s on the way to Kyiv, near the border with Belarus – is a prime example of Russian incompetence in this ‘special military operation’. As to Zaporizhzhia in the south-east, Europe’s largest nuclear power plant, the situation is very murky, with Russia claiming it has complete control of it and Ukraine emphatically denying this claim. It has been regularly shelled, presumably by the Russians, and nearby residents have been evacuated recently.

Jacinta: Yeah, here in Australia we never think of warfare being a threat to the nuclear industry, it goes to show, you never know. Of course power supplies will always be a target in war, but it’s extra problematic with nuclear power – why we shouldn’t rely on it, unless we went the bonobo way pretty damn soon re our social evolution… Yes, the Croatia-Bosnia issue is all about waste dumping. It’s not about warfare or anything, just increased tensions, and the general nimbyism that goes with all this, if that’s not being too dismissive. It’s Croatia that’s building the waste facility near the Bosnian border, and the worries are about public health, local agriculture and their river systems.

Canto: So to get back to the fossil fuel issue, because of increased energy demand overall – and that’ll continue for a good while – we’re releasing more CO2 into the atmosphere, at increasing rates, even while our percentage of energy demand that’s met by fossil fuels is going down. So, fat chance of reaching our targets – generally considered as no more than 1.5 degrees above pre-industrial temperatures by – whenever. Others are giving up on that and talking about 2 degrees, which many consider more or less catastrophic.

Jacinta: They say that currently 75% of the world’s energy comes from fossil fuels. Uhhh, that’s not an exact figure. And some fossil fuels are worse than others, as we’ve said.

Canto: And at this rate, our emissions will almost double by 2050. And battery electric, and hydrogen, will require more fossil fuel emissions to produce. Nuclear could be an option there, but it’s unlikely everyone’s going to get on board with nuclear.

Jacinta: And, as Steve Novella points out, all of these new renewable energy projects – wind and solar in particular – are involved in a backlog to get onto the grid. There just isn’t enough grid electricity to cover new projects, and upgrading the grid to cope with varied, and variable, forms of energy, is a major, time consuming project in itself. And that’s leaving aside all the political machinations going on, the vested interests and so forth. We’ve just recently allowed fracking to go ahead in the Northern Territory, and so it goes…
